  Pasting without resizing layer boundary (new behavior in 2.10???)
Posted by: traycerb - 06-16-2020, 04:56 AM - Forum: General questions - Replies (5)

I have a layer which is 600x600 (size of a passport photo), and I paste a larger image (a person's portrait), which I resize so the person's face fits in the boundary.  Other parts of the photo (e.g. above the head and below the neck) are not relevant for this purpose.

It used to be (2.8.xx) that after my resizing and then finally anchoring the selection to that layer (clicking outside the pasted area), the pasted part of the image outside the layer boundaries was cropped out.

However, I just updated to 2.10, and when I paste the image to the layer, the layer's boundary adjusts to the size of the pasted image.  I tried locking the layer, but then I can't paste into it.  Is there some setting to revert to the previous behavior??  Huh  I depended on the window/auto-crop behavior, which gave me exactly the size image I needed.

  PyGimp on Focal Fossa
Posted by: Ofnuts - 06-15-2020, 10:52 PM - Forum: Linux and other Unixen - Replies (3)

When I was on (K)Ubuntu 16.04 and sentenced to use 2.10 in a flatpak I found it too limited compared to the standard version, so since I plan to upgrade my 19.10 ot 20.04 before year end I just hacked my way to "full" Gimp-cum-Python support in a 20.04 VM, by adding required files copied from my 19.10. The final boss is having the Python console working (not killed that one yet).

   


I heard that some folks where installing from Debian repos (where Pythonv2 is more alive than on Ubuntu)?

  Unpacking a Gimp appimage
Posted by: rich2005 - 06-15-2020, 11:37 AM - Forum: Tutorials and tips - No Replies

Using an older version of Linux with an equally older version of Gimp?  Want to update Gimp but find the alternative flatpak / snap versions limited?

At the moment there are excellent portable Gimp 'appimage' versions. Downloadable from the Assets folder here: 

https://github.com/aferrero2707/gimp-appimage/releases/

These work by making the file executable and running. More than adequate for occasional use but if you want to create a more permanent version,  the appimage can be unpacked.  That gives certain advantages, a little more flexibility.

That is the purpose of this demonstration video https://youtu.be/F1epWY5SYn0  duration 8 minutes. Shown in LinuxMint 19

  2.10 layer composition options and modes
Posted by: Ofnuts - 06-15-2020, 09:09 AM - Forum: General questions - Replies (4)

The 2.10 release notes say:

Quote:Compositing options for layers are exposed to users now, and all layer-related settings are finally available in the Layer Attributes dialog.



[Image: gimp-2-9-6-layer-attributes-dialog.png]

If I sort of guess the Blend space/Composite space, I wonder what the "Composite modes" do?

These notes also mention new blend modes, but I'm still wondering what these do: Erase, Exclusion, Merge, and Split. Exclusion seems to be some kind of "xor", but I can't even find an case where the other three have a visible result.

  layergroup managing scripts
Posted by: dela - 06-15-2020, 07:19 AM - Forum: Extending the GIMP - Replies (2)

Hello,

I am looking for scripts to manipulate layers and layergroups.

examples

1] Non destructive renaming/renumbering layers ( adding numbers to the layers *001*, moving copy del etc, remove numbering which gives the layer it's original name,
ic removing *xxx*)

2] Moving and/or Copying layers into a layergroup ( simplest format usable would be,  move xxx layers below it into a layergroup )

3] Copying layers and layersgroup ( copy layers from *010* to *020* the layergroups contained in this area must also be copied )


I have found scripts which number but they can't remove the 'added' numbers.
I have found scripts which copy layers but from layergroups only the 'top' layer is copied.


Smile  mostly using 2.8 with layergroups, occasional 2.10

  Changing opacity of floating dialogs
Posted by: migf1 - 06-14-2020, 09:01 AM - Forum: General questions - No Replies

Hello,

is there a setting to adjust the transparency of floating dialogs, like the one that pops up when entering text? https://prnt.sc/szee1g

I'd pretty much prefer them to be opaque.

Thanks!

  Stylizing GtkNotebook Tabs in Theme (gtkrc)
Posted by: migf1 - 06-13-2020, 06:41 PM - Forum: General questions - Replies (23)

Hello,

I actually subscribed to ask you guys this, but frankly I don't know if this is the right forum. If not, I would appreciate some pointers to the right place(s). Thanks in advance.

Long story short (and for the name of the loving God) I cannot find which widget corresponds to the tabs of a GtkNotebook in the gtkrc file (and hence to the GimpDockbook, since according to the docs it inherits the styles of the GtkNotebook).

With lots of trial & error attempts, I figured that the widget_class "*<GtkNotebook>.<GtkWidget>.<GtkLabel>" affects the labels of the tabs (their text title) but what I'm after is how to highlight the active tab, as shown in the Gtk2 docshttps://developer.gnome.org/gtk2/stable/notebook.png (that little blue stripe, at the top of the active tab)

Btw, the full docs are here: https://developer.gnome.org/gtk2/stable/...ebook.html

I can colorize the actual pane of the active tab (the white area in the image above), as well as the background color of the inactive tabs., But I cannot find how to make that little highlight at the top of the active tab.

The funny thing is that I had done that, like 6 years ago, in a collection of themes for Gimp 2.8 I had released on DeviantArt. I had many requests to update them for v2.10.1x, which I kindly declined, because I have never dealt with the GTK2 theming engine since then.

However, like a week ago, I decided to give it a go (using Gimp 2.10.18) but I found that things I've done in the old themes do not work now (most probably because GTK+2 has evolved since then and/or because newer versions of Gimp probably use some things differently).

I've almost finished a Dark theme for Gimp 2.10.18, for which btw, v2.10.20 broke the ComboBox drop-down lists style. Most notably the appears-as-list property (which has been reported as problematic and it's deprecated in GTK3). In Gimp 2.10.18, with that property set to FALSE, all ComboBox drop-down lists were using the styles of the menus, so they were looking like popup menus. You know, the ones with the scrolling butons at their top and bottom, like the list of the layer Blend Modes in v2.10.18. In Gimp 2.10.20, regardless of how I set the "appears-as-list" property, all ComboBox drop-down lists look like regular TreeView lists, and once again I cannot find how to disable the border/shadow around the popup: https://prnt.sc/sz5e7a

So, that's a second thing I would like to know how to solve, if possible.

I've tested Gimp 2.10.20's default dark theme, and I confirmed that indeed the layer Blend Modes list has been brought back to be a regular list (its appears-as-list property is set to FALSE, but changing it to TRUE doesn't make any difference, just like it doesn't with my theme anymore). The reason it looks as a popup menu is because the default themes overlay everything with images (found in the ./ui/ folder). I guess going for uniform looks across different OSes, so menus and TreeView lists are both using the same background image. But if you look for it you will see that in Gimp 2.10.20 the layer Blend Modes list does NOT have top & bottom scrolling buttons. Instead, it uses a regular vertical scrollbar, so it is a just a list.

Please excuse my long post, I tried to be as precise as I could, about my questions. Once again, if you know a better place I should ask, please let me know.

Greetings to all!
